* Every time we create a new router identity, add an entry to the
      new "identlog.txt" text file in the I2P install directory.  For
      debugging purposes, publish the count of how many identities the
      router has cycled through, though not the identities itself.
    * Cleaned up the way the multitransport shitlisting worked, and
      added per-transport shitlists
    * When dropping a router reference locally, first fire a netDb
      lookup for the entry
    * Take the peer selection filters into account when organizing the
      profiles (thanks Complication!)
    * Avoid some obvious configuration errors for the NTCP transport
      (invalid ports, "null" ip, etc)
    * Deal with some small NTCP bugs found in the wild (unresolveable
      hosts, strange network discons, etc)
    * Send our netDb info to peers we have direct NTCP connections to
      after each 6-12 hours of connection uptime
    * Clean up the NTCP reading and writing queue logic to avoid some
      potential delays
    * Allow people to specify the IP that the SSU transport binds on
      locally, via the advanced config "i2np.udp.bindInterface=1.2.3.4"
